Patent number: 9961915Abstract: Methods and systems for treatment of grain for toxins and/or odor utilize a storage container having a grain storage space and an aeration floor that allows air to flow through the aeration floor into the grain storage space. Ozone (mixed with air) is supplied to the grain through the aeration floor under positive pressure, whereby ozone is forced through the aeration floor into a lower portion of the grain storage space. After an initial treatment time, the initial treatment time allowing for the ozone to reduce toxins and/or odor in a lowermost portion of the initial quantity of grain an effective or desired amount, a lowermost portion or a lower treated portion of the grain in the grain storage space is removed, and new grain is added on top of the grain in the grain storage space, all while continuing to supply ozone through the aeration floor under positive pressure.Type: GrantFiled: December 22, 2009Date of Patent: May 8, 2018Assignee: Archer Daniels Midland Co.Inventors: Lynn Johnson, DelRon E.

Patent number: 9808020Abstract: Methods and systems for treatment of grain in a storage container using ozone may be used for treating grain for toxins, insects, mold, and/or odor. Downdraft methods for applying high concentrations of ozone to grain in a storage container treat grain without generating ozone-related objectionable odors or with generation of only minimal ozone-related objectionable odors. A method for downdraft ozone treatment of grain with minimal generation of ozone-related objectionable odors involves providing a negative air pressure at a bottom of a volume of grain in a storage container. A high ozone concentration is generated in air above an upper surface of the volume of grain. The ozone is drawn down into the volume of grain using the negative air pressure for a treatment time sufficient to effectively treat the grain without causing significant ozone-related commercially-objectionable foreign odors in the grain.Type: GrantFiled: March 3, 2010Date of Patent: November 7, 2017Assignee: Archer Daniels Midland Co.Inventors: Kevin C. Johnson, Lynn Johnson, Delron E. Albert, Vane Case

Patent number: 9808021Abstract: Systems and methods for treating grain stored in a grain pile with ozone are effective for treating grain for toxins, insects, mold, and/or odor. A method according to embodiments of the invention involves monitoring at least one of temperature and odor at a plurality of aeration outlet locations spaced around the grain pile. When an abnormal temperature variance or odor is detected at one or more of the aeration outlet locations, a determination is made as to a problem location within the grain pile where a treatment of ozone should be applied, and a further determination is made as to how best to apply ozone to the problem location. Ozone is then applied to the problem location within the grain pile to minimize nascent problems in the grain pile. The ozone treatment may reduce molds and toxins.Type: GrantFiled: March 3, 2010Date of Patent: November 7, 2017Assignee: Archer Daniels Midland Co.Inventors: Kevin C. Johnson, Lynn Johnson, Delron E.

Patent number: 9732163Abstract: Described herein is an ethoxylated starch crosslinked with a cross linking agent having surprisingly high viscosity in water. The ethoxylated crosslinked starch described has a degree of ethoxy substitution from 1% to 3% and the crosslinking agent is from 0.02% to 0.05% of the weight of starch. Within this narrow range of values, a 7% wt/wt aqueous solution of the crosslinked ethoxylated starch exhibits a viscosity of at least 1600 cps at 95 ° C. This ethoxylated crosslinked starch is particularly useful in the formation of ceiling tiles with stucco, borax and steel wool, and should be useful in enhancing the viscosity of hydraulic fracturing fluids.Type: GrantFiled: January 2, 2014Date of Patent: August 15, 2017Assignee: Archer Daniels Midland Co.Inventor: James McClain

Patent number: 9228178Abstract: Recombinant genetic constructs and strains of H. polymorpha having significantly increased ethanol productivity with a simultaneous decreased production of xylitol during high-temperature xylose fermentation are disclosed. The constructs include a H. polymorpha XYL1 gene encoding xylose reductase mutated to decrease affinity of the enzyme toward NADPH. The modified version of XYL1 gene under control of a strong constitutive HpGAP promoter was overexpressed in a ?xyl1 background. A recombinant H. polymorpha strain overexpressing the mutated enzyme together with native xylitol dehydrogenase and xylulokinase in the ?xyl1 background was also constructed. Xylose consumption, ethanol and xylitol production by the constructed strain were evaluated during high-temperature xylose fermentation (48° C.). A significant increase in ethanol productivity (up to 7.4 times) was shown in the recombinant strain as compared with the wild type strain.Type: GrantFiled: June 1, 2009Date of Patent: January 5, 2016Assignee: Archer Daniels Midland Co.Inventors: Charles Abbas, Kostyantyn Dmytruk, Olena Dmytruk, Andriy Sibirny, Andriy Y.
